Final answer:
If Twin A is in breech position, a Caesarian section is commonly preferred today for delivery, as it is considered safer for both mother and infant.
Step-by-step explanation:
If Twin A is in breech position, which means the baby is oriented buttocks down, there are specific protocols that healthcare providers may follow. Historically, vaginal delivery was common for breech presentations, but modern practice often prefers a Caesarian section for the safety of both the mother and the infant. In fewer than 5 percent of births, breech presentation occurs and it can be classified as either a complete breech, where both legs are crossed and oriented downward, or a frank breech, with legs oriented upward.
